The latency that is calculated via the (getlatency) message to supervp.scrub is incorrect.
It seems to be twice the actually latency (i.e dividing by two seems to correct it).
At window sizes above 8192, this fix does not work and the latency is off by several 1000 samples. In the reference it states that the latency is output in ms, which is incorrect.
